Charlie, You might want to take a look at Valor. They have Package naming based on JEDEC/EIA standards already cataloged on an SQL-based library. Although the software takes you through the entire process of Data integration through Machine op

Yea. I think that http://www.topline.tv/SMDnomen.pdf is even better. But the problem is that these two files was done in 1998 and from that time 0402 its not a prototype anymore its a standard. I would like to have this kind of document but more curr

I previously did a search on "peel back force" and there were a few results, and there were a few hits that say EIA-481 is the standard, but nothing on what the standard force range is. A search on "cover tape" yeilds many hits about breaking cover

I have always referenced the following tape and reel specificatons for automated handling: Axial - EIA 296 Radial - EIA 468 SMD - EIA 481

Greetings, Does anyone know where to find a tape and reel flatness specification? Looking at the EIA 481-B standard, there is no reference to the tape flatness (the images shown may "imply" flatness from one side of the tape to the other, However I

Ken, Excellent discussion!!! I've also seen this problem. Spent and am still spending significant time policing. I don't think it is just a buyer issue though. There are many dimensions to the problem. Suppliers, Engineering, Manufacturing, and

Hi, I need support on the method or applicable standard to measure the shear force strength on chip capacitors and resistors. I know the soldered joints strength is related to land desing, solder volume, pcb and component solderability, component

Yes Davef, storage condition and long time remaining on shelf could effect pealing strength, but we experimented that by using Polystirene Carrier Tape also this problem was reduced almost to zero. Df, If I am not wrong when you talk about pr

VTEK says …” Carrier tapes are made from three primary materials. (All are manufactured in accordance with EIA standards) 1 Polycarbonate is a black plastic material with excellent impact strength. It is used primarily for bare die and small form fac
